🧾 What This Document Is

This is a 6-K form, a report that foreign companies listed on U.S. exchanges (like Loma Negra on the NYSE) must file with the SEC to announce "material events." Think of it as a major announcement letter to investors and regulators.

👉 In simple terms: This filing discloses a sudden and complete overhaul of the company's Board of Directors, which is the group that oversees management.

🏢 What The Company Does

Loma Negra is Argentina's largest cement, concrete, and aggregates producer. It's a critical building materials company in the region. As an Argentine company with shares trading in New York (as an ADR, ticker: LOMA), it must keep U.S. investors informed of major corporate changes.

🚀 The Big Shake-Up: A Whole New Board

On April 6th, 2026, the entire leadership of the board resigned. This includes:

• Paulo Sergio de Oliveira Diniz (Chairman)
• Laura Gé, Humberto Junqueira de Farías, Javier Enrique Patrón, Sergio Daniel Alonso, and César Javier Graña (Directors)

This left the board unable to function. The company's Supervisory Committee (a governance body) used special powers to immediately appoint a brand-new board to keep the company running until the next shareholder meeting.

👥 New Board Structure

A new, nine-person board was appointed and quickly organized itself on the same day.

President: Marcos Marcelo Mindlin (Non-Independent) Vice-president: Sergio Damian Faifman (Non-Independent) Independent Directors: Darío Gustavo Epstein, Juan Pablo Trujillo, Diego Dayenoff, and Gregorio Charnas. Non-Independent Directors: Fernando Tisné. Alternate Directors: Andrés Mindlin, Sean Mulroy, and Christopher Theuerkauf (all Non-Independent).

👉 Key Detail: The board is a mix of "independent" directors (who have no material relationship with the company) and "non-independent" ones. This balance is required by U.S. and Argentine rules to protect investor interests.

📊 New Audit & Financial Expert

The new board also formed a new Audit Committee (the group that oversees financial reporting and audits):

• Chairperson: Darío Gustavo Epstein (Independent)
• Vice-Chairperson: Juan Pablo Trujillo (Independent)
• Member: Gregorio Charnas (Independent)

Crucially, the filing notes that Darío Gustavo Epstein qualifies as an "Audit Committee Financial Expert." This is a specific, SEC-required designation for someone with the right financial expertise, which is a positive signal for financial oversight.

⚖️ Why This Matters: Strengths & Risks

This is a dramatic event. Here’s how to think about it:

👍 Potential Positives (Strengths):

• Clean Slate: A complete board change can signal a strategic reset or a resolution of internal conflicts.
• Immediate Action: The quick, legal process to appoint a new board prevents operational paralysis.
• Independent Oversight: Having a majority of independent directors on the new board, especially on the Audit Committee with a designated financial expert, is good for corporate governance.

⚠️ Key Concerns (Risks):

• Mass Resignation: The simultaneous resignation of the entire board is highly unusual and suggests significant, unresolved issues—which could be strategic, financial, or personal.
• Uncertainty: Investors don't yet know the reason for the resignations or the new board's strategic vision. This creates a vacuum of information.
• Execution Risk: A sudden change at the top always introduces a period of transition and potential instability as the new team gets oriented.

🔮 What's Next & Broader Implications

The immediate crisis of leadership is solved, but big questions remain. Investors will be watching closely for:

• The "Why": Any further explanation for the sudden resignations.
• The Plan: Statements from the new President, Marcos Marcelo Mindlin, and the board about their strategic direction for the company.
• Stability: Signs that this change leads to decisive action or, conversely, to further turmoil.

👉 What This Signals: This isn't a routine board refresh. It's a fundamental change in the company's control and oversight structure. The speed of the replacement suggests the major shareholders or stakeholders were prepared and wanted to avoid any gap in governance, which is a stabilizing move after a destabilizing event.

🧠 The Analogy

Imagine a professional soccer team's entire coaching staff and front office—manager, head coach, all assistant coaches—resigning simultaneously in the middle of the season. The league appoints a new, emergency front office to run the team until a permanent solution is found. The players (operations) keep playing, but fans (investors) are anxiously waiting to hear the new strategy and understand what went so wrong to cause the old regime to leave all at once.

🧩 Final Takeaway

Loma Negra has executed a complete, overnight change of its entire Board of Directors following a mass resignation. A new, mixed board of independent and non-independent directors, featuring a certified financial expert leading the Audit Committee, has been swiftly installed to maintain control. The company is stable for now, but the reasons behind this drastic move are the critical unknown that investors must watch.
